Project: Hilo Spurs

Sandwich Isles Communications, Hilo, Hawaii

Underground Construction Co., Inc. in partnership with Island Mechanical Corporation installed a fiber optic conduit system in Hilo, HI. Our project was part of a $400 million network being constructed by Sandwich Isles Communications, Inc. on the Hawaiian Islands. The land based fiber-optic network linked all the Department of Hawaiian Home Lands properties and was connected to adjoining islands by undersea cables. This system provided state of the art Telephone Service and Internet access for their subscribers.

Nearly half the project was installed by directional drilling. Island Mechanical utilized a Ditch Witch 4020 and 2720 directional drilling machines to install the conduit system in the extremely abrasive lava rock. Hydraulic excavators were also utilized in the limited access areas, as well as Hydraulic Hammers. The 1-1/2” and 1-1/4” HDPE duct system was installed in the shoulder area of State and County roadways. We were awarded an additional 2.5-mile section that consisted of a manhole system in commercial and residential neighborhoods.
